Ambience and substrates for the development of pepper seedlings (Capsicum chinense Jacq.)

Abstract

In order to evaluate the influence of different environments and substrates on the production of chili pepper seedlings, an experiment was installed in a completely randomized design (DIC), with treatments arranged in subdivided plots. Five environments were evaluated: EA - agricultural greenhouse; TV35 - red screen with 35% shading; TV50 - red screen with 50% shading; TP35 - silver screened with 35% shading and TP50 - silver screened with 50% shading, and four substrates: S1 - OrganoAmazon®; S2 - OrganoAmazon® and PuroHumus®; S3 - OrganoAmazon, PuroHumus, soil and manure, and S4 (OrganoAmazon®®, PuroHumus®®, soil, manure and carbonized rice husk). In the photoconverter meshes TP35 and TP50, the pepper seedlings grown in the substrate S2 provided high IQD. The combination of agricultural greenhouse (EA) and S3 substrate promote superior quality chili pepper seedlings. S4 and S3 substrates are more affordable alternatives to the production of chili pepper seedlings. The photoconverter screens, associated with alternative substrates, do not favor the production of quality pepper seedlings.
